I am trying to use the ProIV Mail active x control and I am curious on using it? It is registered and ready to go, but I have found with the active x controls that there is no documentation about implementing their methods.

I have been succesful with the tree control, rich text box ( except scrollbars ), and the proiv browser. Has anyone had any success stories with other active x controls?

thanks

We have just become succesful with the ProIV mail active-x control.


Later.

Neil,

What were the problems. I am surprised you didn't get a reply to your post. Seems to me mail would be a popular item.

Lew,

We had to set the UseRedemption property of the ActiveX control to false.

We have also been able to incorporate a Crystal Reports Viewer if anyone is interested.

hi,

We would be interested in this.

Can you please provide some details, such as the version of crystal it interfaces with and what it does.

regards

Crystal Reports 8.5
Loads and displays live reports using an ActiveX control NeilIV and I created in VB 6.0

We have now got the PROIV.CSPGrid grid control to work. It has some great features compared to the Listbox in VIP. You can use the mouse to select rows and columns and formatting is cool.

The OCX is CPROIVSPGrid.ocx.

Yeah the Grid is pretty cool but has a few annoying drawbacks - if you alt-tab to another application in windows it loses focus so you have to click on the cell you were editing again.

Also it's a shame that Pro-IV didn't expose more of the properties, methods and events that #Grid has available - some of them (such as an event on Grouping) would be really handy.

I wrote a file browser utility - enter a file name and it creates a function on the fly (and Pro-IV says we don't need the bootstraps!) using a grid to enter the keys and another grid to display the data from the file. The grouping option is dead handy for finding all the records with the same field value for testing purposes.

Last night I was trying to implement a Pro-IV progress bar for when the data is loading and came across a few anomalies:

Having the grid installed in a function seems to interfere with using LINK to call external C routines compiled into the kernel. We have one called GETRECS that counts the records in a C-ISAM file. In a function with the Grid Pro-IV no longer recognises the routine and says it doesn't exist...

Also, I wanted to include a Pro-IV progress Bar to display while loading data into the Grid. I had a one-time window cycle with the Progress Bar in the Format and nested within the window an update cycle to read the file and do the Grid.RowAdd() and a ProgressBar.Step() so the record would be loaded and the Bar move on. But for some reason (despite reading all the records) the Grid loses the data and nothing displays.

I think it'll be a couple of versions before the Active X is totally stable but it's still a great addition to the language.

Stuart, the grid control I am using has a grouping header on it. You grab the column header of the field you want to group and drag it to the top and it does a really neat grouping.

I have noticed that there are a few grid active x controls and it may be a question using the right one. I am currently not using the control to edit fields, but I am calling global functions when I click into a few different cells.

I am using Oracle tables.

But for some reason (despite reading all the records) the Grid loses the data and nothing displays.

I have had to add an extra row to have an "event" fire so to speak and display my newest data. Before, I would have to click on the control and the new stuff I changed would then appear.

Are they ( active x controls ) totally stable, probably not, but neither is VIP.

The Grid I'm using is the #Grid supplied by Pro-IV. It has the grouping ability which is great but it would be nice to have an event fire when group is used. In my screen I have two buttons at the button, Expand and Contract. It would be nice to be able to grey those buttons out when there are no groups being used. The best way to do that would be if dragging a header to do a group caused an event to fire which would have a logic attached with Button.Enabled = False.

My problem with the Grid not displaying data is only when I wanted to do the Progress Bar. Otherwise it's OK.

It appears that calling another screen cycle causes Pro-IV to forget about the Grid control so the Grid.RowAdd doesn't work...

I think the problem of the Grid losing focus when alt-tabbing between apps could be a feature of Active-X in Pro-IV rather than the Grid itself. You may have noticed a similar problem when editting a logic in VIP (you alt tab to copy something from another session and when you go back the cursor is no longer on the editor - you have to click again before you start typing).

Must be more to it. We have several functions that use progress bar while bulding a grid. They
are arranged in a similar manner to what you described. But the controls we use are not the
standard P4 ones, they have all been wrapped for our purposes and we use a 3rd party GRID.

[Stuart Burton]

Hi Chris!

What grid control are you using? Did you have to buy it or is it a free one?

So far we haven't had a need to use it in a real application (I've just been testing out the new features for possible future use) as we do mostly green screen and we've only recently upgraded to 5.5.

[NeilIV]

The OCX is CPROIVSPGrid.ocx. CPROIVSPGrid Active x control module ( V1.0)

This is the one we use.

[Chris Mackenzie]

Our controls are all customised by VB programming staff. I don't know what they
had to do to make them work but they do!

the grid is called 'SharpGrid' from Data Dynamics and the progress bar is
standard MSProgress (miscrosoft windows common controls 6.0 (v2.0)).

[Stuart Burton]

The SharpGrid is the one that comes bundled with Pro-IV. Pro-IV have created a special wrapper for it and that's the version you get (with reduced functionality).
